Postalloy® Durachrome-G
A premium metal-cored, gas-shielded chromium carbide hardfacing alloy that has a high volume fraction of carbides dispersed in a hard matrix. Excellent out-of-position weldability. For applications involving high abrasion and mild or moderate impact. Deposit polish in service and are heat resistant to 1000°F (538°C). Use on carbon and low alloy steels. When used with 100% CO2 or 75/25 Argon/CO, it offers excellent weldability in flat, horizontal and vertical down positions, the arc is very stable at both high and low voltages settings, and the smoke level is very low.

Welding Parameters
Current Type: DC Electrode Positive
Volts | Amps | Diameter | Stick Out |
---|---|---|---|
18-26 | 140-260 | .045" (1.1mm) | 3/4"-1"(19-25mm) |
22-28 | 200-280 | 1/16" (1.6mm) | 3/4"-1"(19-25mm) |
Welding Procedure:
When welding out of position, use .045 with reverse polarity and the lower range of amperages and voltages. Weld vertical down with 3/4"(18mm) wide weave beads.
